Generally speaking, most people will notice the digestive benefits within the first month of taking a probiotic. You may notice more regular bowel movements, less gas and bloating and even a better sense of well-being.
If you are taking a probiotic to help alleviate antibiotic-associated diarrhea or for travelers diarrhea you likely will notice the benefits within the first few days.
For those taking probiotics to help with Crohn’s, Colitis or IBS symptoms, be patient and allow at least 3 to 4 weeks to gauge the benefits.
Probiotics can also support the health of the immune system and this effect could be noticed within a few months with less respiratory infections during the cold and flu season.
Consistency matters so take your probiotics daily to achieve the best results.
